We all knew Gregg Popovich was old school. We just didn’t know how old school

Like 1970s old school. Like Steve Martin doing King Tut on Saturday Night Live old school. Like The Who when they still had Keith Moon as their drummer old school. (Actually, that last one is not a bad school to be in.)

“I’m old-school, I wish there weren’t any threes,” Popovich said. “It would be more basketball-like to me.”

We should note — as does the Spurs blog — that this season’s Spurs revival would be going nowhere fast without the three.

Heading into the final two games of the season, the Spurs rank fourth in the NBA in 3-pointers made and first in accuracy (39.9 percent).

Two players have set career highs in 3-pointers made, Richard Jefferson (133) and George Hill (77). Manu Ginobili (154) needs three more to set a career best. Matt Bonner leads the league in 3-point accuracy (102 of 224, good for 45.5 percent), while Gary Neal has connected on 126 long balls, tops among rookies.

Popovich’s overarching theme for his team is noted — they need to get points in the paint to balance out those threes in the playoffs or the team is in trouble.

But his team knew that. This is a veteran bunch. Some of them may even remember Steve Martin doing King Tut on Saturday Night Live.

That’s a fine sentiment. Saying it publicly is another matter. Not even Harden did that a couple years ago. He was recorded during a pregame team huddle.

There’s a fine line between self-fulfilling confidence and providing bulletin-board material to the opponent. There’s already some animosity between the teams stemming from the Stephen Curry-Harden MVP race in 2015, and it has bubbled since. No matter how harmless Capela’s remark might have been intended to be, it’ll be met contentiously in the Bay Area.

Oklahoma City traded for Victor Oladipo out of Orlando to be their third scorer, behind Kevin Durant and Russell Westbrook. It didn’t exactly work out that way, Durant bolted town and when Westbrook went off Oladipo was looking for a place to fit in.

That place turned out to be the Pacers.

Oladipo has been playing like an All-Star this season with Indiana, and last week he was key in snapping Cleveland’s 13 game win streak, then turned around and dropped 47 points on Denver. For the week he averaged 35.7 points a game, shot 45.7 percent from three, plus grabbed 7.7 rebounds per game.
